We know that sum of adjacent angles 180°,

therefore angle AOB= angle AOD+angle DOB

180°=90°+angle DOB

angle DOB=90° .......(1)

and angle DOC=angle DOB+ angle BOC

180°=90° +angle BOC

angle BOC=90°.

angle BOC=angle BOQ + angle COQ

90°=2 angle COQ

angle COQ=45°

similarly angle POC=45°

Therefore angle POQ=angle POC+angle COQ

angle POQ=45°+45°

angle POQ=90°.

Hence proved.
